Title: Formation of shell core
Inventor: SAKAI SHIYOUJI
IPC: B22C9/10
Filed: 1981-08-26
Abstract: PURPOSE:To provide a method for forming cores which permits removal of blow ports in one touch after forming of the cores by providing the blow ports for shell sand on the side parts of the cavities of dies for forming shell cores. CONSTITUTION:Dies for formation of shell cores are constituted of a top part and a bottom part 2 parted by a parting line 3 and the cavities 4, 5 between the parts 1, 2. Blow ports 6 for the purpose of blowing shell sand into the cavities 4, 5 are provided approximately vertically in the side parts of the cavities 4, 5,  and sand grooves 7 for the purpose of distributing the shell sand supplied into  the ports 6 into the cavities 4, 5 are provided along the line 3 in the botoom end  parts of the ports 6. For example, in the case of manufacturing cores 8 for  water jackets for engines, shell sand is blown through the sand grooves 7 provided in the side parts of the straight line parts viewed flatly. Therefore the  traces of the grooves 7 remaining slightly in the traces where the grooves 7 are broken off from the cores 8 are finished easily simply by using tools such as  files.

Title: Hot-air blow-off device for box type stove
Inventor: OSADA KOUTAROU
IPC: F24H3/02
Filed: 1982-07-31
Abstract: PURPOSE:To suck and mix hot-air and room air simultaneously and blow off the hot air having a comfortable temperature by a method wherein a hot-air outflow path, having a blow-off port at the tip end thereof, is projected obliquely, downwardly and forwardly from the upper part of front face and a cross-flow fan, having the suction port therefor at the bottom surface and the lower part of the front surface thereof, is provided. CONSTITUTION:The left and right legs 34 of the hot-air blow-off device 1 are adhered to a flat plate part at the outside of the releasing port 42 of hot-air, which is located at the rear part of the upper surface 41 of the box type stove 40, by magnets 35. When an operating switch is put ON and a motor is driven to rotate the cross-flow fan 2, the air, at the bottom side of a casing 1, is sucked upwardly. Cold air 46 in a room at the rear side of the stove is induced through a suction port 18 while the hot- air 47 of the stove 40, released to the front side of the cold air, is induced through the suction ports 21, 15. The cold air 46 and the hot-air 47 are mixed during flowing and are sent into the outflow path 29 from the upper part of the casing 1 as the hot-air having a temperature somewhat lower than the same of the hot-air itself released from the stove 40, and the hot-air is blown off forwardly, obliquely and downwardly from the blow-off port 22.

Title: High-frequency rotary transformer
Inventor: ITO YOSHIO
IPC: G11B5/02
Filed: 1985-06-20
Abstract: PURPOSE:To narrow a short ring groove to widen the facing surface except the groove surface, by arranging the short ring, without being completely housed inside the groove, so that it projects from one side of the surface on which a stator core and rotor core face each other. CONSTITUTION:While a short ring groove 4 is made large enough for positioning, without a short ring 6 completely housed inside the groove, the short ring 6 is fixed with an adhesive or the like by utilizing a gap DELTAt so that it projects from the surface of a stator core 1. Since this composition allows the width S1 of the short ring groove 4 to become smaller than the diameter of the short ring 6, the short ring groove can be narrowed, and resultantly the surface except the facing groove surface becomes widened to improve a coupling coefficient between a rotary transformer and rotor.stator, and therefore this composition is available for improvement of picture quality when used in VTR.

Title: Solid state image pickup device
Inventor: SATOU KAZUO
IPC: H04N5/335
Filed: 1982-08-04
Abstract: PURPOSE:To ensure free selection of the scanning direction and to facilitate the easy electric processing for picture of an optical image, by providing horizontal and vertical reading circuits which are set backward to each other for free selection of the reading direction. CONSTITUTION:A horizontal clock pulse 7, a horizontl transfer clock pulse 8 and a horizontal start pulse 9 are applied to a horizontal shift register 19 as well as a horizontal shift register 4. However the register 19 has its transfer direction adverse to the register 4 for scanning to obtain a signal output 6. Therefore the signal of each photodetecting diode is read out and scanned backward for the output signal 6. This obtains a picture which is adverse symmetrically to the image of a object. In the same way, a vertical shift register 24 has its transfer direction opposite to a vertical shift register 5 for scanning. Thus a picture which is adverse vertically to the object image. These pictures are selected with a switch among input control signals 17, 18, 21 and 25 respectively.

Title: Picture signal processing circuit
Inventor: SUGIYAMA MASAHITO
IPC: H04N9/64
Filed: 1988-06-03
Abstract: PURPOSE:To obtain high picture quality by selecting the output signal of a frame memory as a signal to previously execute YC separation at a comb line filter circuit and to be the reference of another signal for an animation when a non-standard signal is inputted. CONSTITUTION:When the non-standard signal is inputted, a synchronizing signal generating circuit 3 generates a clock phase-locked into a horizontal synchronizing signal instead of a burst signal, and switching circuits 5 and 6 select the signal to execute intra-field YC separating processing for an inputted television signal and output the selected signal. When the signal for the animation is to be processed, the input signal of a first intra-field processing circuit to execute the YC separation is made into the output signals of delay circuits 8 and 26, and the signal inputted to a second intra-field processing circuit to generate an interpolation scanning line is made into the output signals of second change-over circuits 12 and 29. A signal for a still picture is generated using the output signals of the change-over circuits 12 and 29 and signals obtained by delaying the above-mentioned output signals at delay circuits 16 and 30. Thus, unnaturalness in the movement of a picture caused by the dislocation between the center of gravity of the still picture and that of the animation can be eliminated, and processing for obtaining the high picture quality can be executed even for the non-standard signal.
